Processor or CPU (central processing unit) has functions to read and interpret instructions, melakukak execution, and store the results in memory. CPU data bus used to have 16,32 or 64 bit.
MOTHERBOARD
Motherboard or collectively, the Parent Board Motherboard
is a major component of a PC, because the motherboard was the one
all components of your PC will be united. Motherboard form as
an electronic circuit board. Motherboard is the place passed
lalangnya data. Motherboard connects all the computer equipment and
making it work together so that the computer running smoothly.
Motherboard components
1. Power Connector
Power connector is a pin that connects the motherboard to the power
supply in a computer casing. At AT motherboard type, casing
all it takes is the type of AT as well. AT type power connector consists
of two parts, where the two wires from the power supply will be stuck in
situ. In type ATX, power supply cords together in a single header
intact, so you stay drove it on the motherboard. The cable
consists of two columns correspond to the pin on the motherboard which consists
top two pin arrays as well. There are a few motherboards that provide two
type power connector, AT and ATX. Most recent motherboards already
ATX type.
2. Processor Socket or Slot
There are several types of plugs to plug your processor. Model
the longest is a ZIF (Zero Insertion Force) Socket 7 or opular
with terms Socket 7. This socket compatible processors fib
Intel, AMD, or Cyrix. Processor models are usually used for long
(Up to generation 233 MHz). There is another socket called
Socket 370. Socket to Socket 7 is similar but the pin number
as the name suggests, 370 seeds. This socket compatible processors
Intel fib. While the name itself AMD socket with the term
Socket A, where the pin number is also different with socket 370.
A term used to designate the brand AMD Athlon processor. To
Intel Pentium II processor family and III, slot used
called Slot 1, while motherboard that supports the processor
Slot A AMD uses for such a kind of slots.
3. North bridge controller
VIA VT8751A which provide interfaces prsessor with frequency
533/400MHz, which supports intel Hypertheading tecnologi, interfaces
memory system to be operating at 266MHz, and a 1.5V AGP interface
supports AGP 2.0 specification including protocol with write speeds
4X.
4. Memory Socket
Also there are two types of memory socket that is now circulating in the community
computer. Indeed, there is also the latest socket for Rambus-DRAM but
until now there has been a lot of users who use it. Socket old
SIMM is still quite popular. Socket is comprised of 72 pin modules.
The second socket has 168 pin modules, which are designed in one direction.
You may not install it upside down, because the strain on the motherboard
been adapted to the type of memory DIMM sockets.
5. Floppy and IDE connectors
This connector connects the motherboard to save computer devices
such as a floppy disk or hard drive. IDE connectors in a
motherboards usually consists of two, one is the primary IDE and
the other is the secondary IDE. Primary IDE connector connects
motherboard with the primary master drive and the secondary master device.
Meanwhile, the secondary IDE connector is usually connected with
pirantipiranti to slave and slave drive as CDROM. How
connecting pin with cable? Easy. IDE ribbon cable have
dash of red on one side. The red strip
mark, red striped side of the cable is plugged into the pin numbered 1 in
connectors. When stuck upside down, attached the device will not
recognized by the omputer. The same thing applies to connect
floppy cable with the pin on the motherboard.
6. AGP 4X slot
This image penyelerasi port slot graphics card supports 3.3V/1.5V mode
AGP 4X for 3D graphics applications.
7. South bridge controller
VIA VT8235 integrated peripheral controller which supports various
I / O functions including 2-channel ATA/133 bus master IDE controller,
asmpai 6 USB 2.0 ports, LCP nterface super I / O, and PCI AC'97 interface
2.2.
8. Standby Power LED
This LED is lit when there is standby power on the motherboard. This LED
acts as a reminder (reminder) to turn off the system power
before turning on or off the machine.
9. PCI slots
Pegembangan slot PCI 2.2 32-bit PCI bus master in9i mensopport cart
eperti cart SCSI or LAN with a maximum output of 133MB / s.
10. PS / 2 Mouse Port
This green 6-pin connector is for the mouse.
11. Parallel and Serial ports
In type AT, serial and parallel ports are not united in one
motherboard but connected via cable. So, on the motherboard
available pin for plugging in a cable. Parallel port functions
bermacammacam, ranging from connecting a computer to the printer,
scanner, to connect computers with peripherals
Certain designed using a parallel port connection. Serial port
typically used to connect with a cable modem or a mouse.
There are also other devices that can be plugged into the serial port. In
ATX motherboard type, parallel and serial ports are integrated in
motherboard, so you do not need to plug cables
troublesome.
12. RJ-45 Port
This 25-pin port connects the LAN via a central connector
the network.
13. line-in jack
line-in jack (light blue) menghuungkan to tape player or audio source
other. At 6-channel mode, this jack funsi menjadai bass / middle.
14. line out jack
jack line out (lime) connects to headphones or speakers. On
6-channel mode, this function is a speaker out jack front.
15. microphone jack
mic jack (pink) to synchronize the microphone. At 6-channel mode
This function is a rear speaker out jack behind.
16. USB 2.0 port 1 and port 2
kedu port USB (universal serial bus) 4-pin is provided for
connect with USB 2.0 devices.
17. USB 2.0 port 3 and port 4
kedu port USB (universal serial bus) 4-pin is provided for
connect with USB 2.0 devices.
18. Video Graphics Adapter Port
This 15-pin port is for a VGA monitor or other VGA devices
compatible
19. Keyboard connector
There are two types of connectors that connect the motherboard to the keyboard.
One is a serial connector, while the other one is a PS / 2 connector.
AT type serial connector or a round, larger than the
Model PS / 2 has, with as many as 5 pieces of pin holes. Meanwhile, the
PS / 2 connector has 6 pieces and pin hole diameter is smaller
than half of the AT models.
20. CMOS battery
This battery is used to provide power to the motherboard
recognize the installed configuration, when he does not / has not
get the power from the power supply.
